Mismatch between spec and result

[zmiller91]

There are typos in the spec found at http://www.iab.net/media/file/OpenRTB-API-Specification-Version-2-1.pdf that are being implemented in this project. On page 19 of the IAB spec the "protocol" field is identified as an integer; in the same document on page 48 (video request example) the "protocol" field is defined as an array of integers -- which is correct. I'm also getting issues with the "companiontype" field where I'm passing an array but the code is expecting an int.
